Conteúdo: | The inheritance of resistance to Macrophomina phaseolina was determined using traditional approached and molecular markers. Inheritance studies were based on a cross between the resistant accession BAT-477 and the susceptible accession A-70. Resistance  to M.phaseolina was examined by inoculating bean seeds with soil infested with sclerotia of M.phaseolina. The ratio of resistant to susceptible plants in the F2 population was close to 9:7. Bulked segregant analysis identified two random amplified polymorphic DNA (RAPD) markers linked to M.phaseolina resistance. The first RAPD marker was a 1.6-kb band present in the susceptible and absent in the resistant plants. The second RAPD marker was a 0.9-kb band present in the resistant, but absent in the susceptibleplants.
